Product details
Overview
R5F523E5AGFL#10 from Renesas is a 32-bit RXv2 core MCU optimized for high-precision industrial sensor signal conditioning, featuring dual 24-bit delta-sigma ADCs (DSAD0/DSAD1), rail-to-rail programmable gain instrumentation amplifiers (PGA ×2), 2.5 V low-drift voltage reference, four excitation current sources (50–1000 µA), and CAN 2.0B interface - deployed in temperature transmitters, weigh scales, and RTD/thermocouple measurement systems.
For engineers reviewing the R5F523E5AGFL#10 datasheet, R5F523E5AGFL#10 pinout, R5F523E5AGFL#10 application, or R5F523E5AGFL#10 equivalent, this page delivers verified technical context, package-specific pin mapping (48-pin LFQFP), real-world use-value metrics (23-bit ENOB at 7.6 SPS, ±0.2% current matching), and validated alternative options aligned with IEC 60730 Class B compliance requirements.
Technical Context
The R5F523E5AGFL#10 integrates two independent 24-bit delta-sigma A/D converters with fourth-order sinc filters, simultaneous 50/60 Hz rejection at 10/54 SPS, and inter-unit synchronized start capability - enabling coherent multi-channel sensor acquisition. Its analog front end includes dual PGAs (gain = 1–128), offset drift ≤10 nV/°C, and gain drift ≤1 ppm/°C, all referenced to a 2.5 V ±10 ppm/°C internal voltage source.
Digital subsystems include a 32 MHz RXv2 CPU with FPU (IEEE 754 single-precision), 128 KB flash, 16 KB SRAM, 8 KB data flash, CAN module (1 Mbps, ISO 11898-1), three SCI channels, one RIIC, one RSPI, and ELC-driven event-triggered conversion - allowing low-CPU-load, deterministic timing for safety-critical sensor processing.

Applications
| Industrial Temperature Transmitter | Weigh Scale Load Cell Interface |
|---|---|
|
Use Scenario: 4–20 mA loop-powered transmitter measuring Pt100 RTD with cold-junction compensation. IC Role / Device Role / Timing Role: Primary signal conditioner: digitizes RTD resistance via 4-wire Kelvin sensing, performs linearization, and drives analog output or CAN bus reporting. Use Value: Achieves ±0.1°C accuracy over –40°C to +105°C using matched excitation currents (±0.2%), low-drift PGA (10 nV/°C), and 23-bit ENOB at 7.6 SPS. |
Use Scenario: High-resolution platform scale using 350 Ω strain gauge bridge with digital output via CAN or RS-485. IC Role / Device Role / Timing Role: Precision AFE + controller: supplies excitation, rejects 50/60 Hz noise, computes weight via sigma-delta filtering, and manages calibration storage. Use Value: Simultaneous 50/60 Hz rejection at 10/54 SPS eliminates line-frequency interference; 24-bit resolution resolves <0.001% full-scale changes. |
| Smart Pressure Sensor Node | Motor Phase Current Monitor |
|
Use Scenario: Battery-operated wireless pressure sensor with piezoresistive element and BLE/CAN gateway. IC Role / Device Role / Timing Role: Low-power sensor hub: acquires bridge output, compensates for temperature drift (internal TEMPS), stores calibration in data flash, and wakes on threshold event. Use Value: Software standby mode with LPT wake-up consumes <10 µA; BGO allows background calibration update without interrupting measurement cycles. |
Use Scenario: Inverter-based motor control requiring isolated phase current feedback for torque regulation. IC Role / Device Role / Timing Role: Isolated shunt amplifier interface: conditions current-sense signals, synchronizes sampling across phases via ELC, and feeds data to host MCU via SCI or CAN. Use Value: Inter-unit DSAD synchronization ensures <100 ns skew between phase measurements; 1.4 µs SAR ADC (S12AD) captures fast transient overcurrent events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision sensor signal conditioning applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E5ADFL#30 | Same core, same peripherals, but rated for –40°C to +85°C (D-grade) and uses identical 48-pin LFQFP package | Limited to commercial/industrial ambient environments without extended thermal stress | Select when operating temperature does not exceed +85°C and cost sensitivity outweighs extended temp qualification |
| R5F523E5AGNF#20 | Same functionality and temperature grade (–40°C to +105°C), but in 40-pin HWQFN (6 × 6 mm) with reduced I/O count (16 vs. 20 GPIO) and fewer DSAD differential inputs (4 vs. 6) | Suitable for space-constrained designs where full 6-channel DSAD differential support is not required | Choose for compact PCB layouts where pin count and footprint reduction are prioritized over maximum analog channel density |
Compared with R5F523E5AGFL#10, the D-grade R5F523E5ADFL#30 sacrifices extended temperature operation but retains full analog feature set, while the HWQFN-packaged R5F523E5AGNF#20 trades I/O and DSAD channel count for smaller footprint - making R5F523E5AGFL#10 optimal for thermally demanding, high-channel-count industrial nodes.
